Definitions

  • the invention relates to a drive, hereinafter referred to as of the kind described, for a rotary drum such as a rotary kiln, which rotates about a horizontal or gently inclined axis, and which is mounted on more than two axially spaced pairs of rollers, each roller being driven by a separate hydrostatic motor.
  • a drive of this kind is known from the specification of German Patent Application No. 2,446,941.
  • the drum is only mounted on two roller pairs.
  • the rollers roll, as is normally the case, against live rings on, and spaced along, the drum.
  • the torque is transferred from the driven rollers to the live rings by friction.
  • each roller is driven via a separate power circuit each comprising an hydrostatic motor, a variable displacement hydrostatic pump and a pump drive motor; the torque distribution via the rollers is set at such values that the slip in the individual power circuits lies within permissible limits; and each power circuit includes controls for setting stop, minimum and maximum operating speeds, as well as ramp time between these speeds, corresponding to the torque distribution desired at all times.
  • the torque can in a simple way be determined by measuring the pressure drop over the respective hydrostatic motor.
  • slip in a power circuit in a given operational condition is meant the relative difference between the theoretical oil consumption of the hydrostatic motor and the theoretical oil production of the hydrostatic pump.
  • the slip occurs partly due to leakage in the pump and hydrostatic motor, and partly due to slip in the pump drive motor.
  • the system is self- compensating for the variable gearing between the various drive rollers and the drum, deriving e.g. from temperature difference between the rollers and/or the live rings on the drum.
  • a drum 1 is shown rotationally mounted on roller pairs distributed in known manner and separated from each other in the axial direction of the drum.
  • the drawing shows only two roller pairs 2,2 and 3,3 running against live rings 4 mounted on the drum although there will be further roller pairs.
  • the drum 1 is driven via drive rollers 2 by hydrostatic motors 5, of which only one is shown, mounted at one end of a shaft 6 of the drive roller, which end projects from one of the bearing houses 7 of the roller.
  • Each hydrostatic motor 5 is part of a separate power circuit comprising a variable displacement hydrostatic pump 9 and e.g. a squirrel-cage motor 10.
  • the power circuit has controls, not shown, but known per se, adapted for setting stop, minimum and maximum operating speeds as well as ramp time between these speeds, corresponding to the torque distribution desired at all times.
  • the torque outputs of the various power circuits may thus differ from one another.
  • the power circuit will try to increase the speed within the slip of the circuit and vice versa.
